狭义相对论教学中事件绝对性辨析——以“同时佯谬”为例

Analysis of the absoluteness of event in special relativity teaching——Take the“simultaneous paradox”as an example

相对论时空观是狭义相对论教学的核心内容.物理事件是讨论相对论运动问题时的抽象概念,对事件及其绝对性的认识程度将影响学生狭义相对论时空观的建立.本文通过在狭义相对论教学中介绍一个具体的“同时佯谬”案例,强调事件本身不依赖参考系,参考系用于事件的时空坐标描述,帮助学生认识事件的绝对性,建立相对论时空观.

conception in the discussion of relativistic motion.The degree of understanding of event and its absoluteness will affect the establishment of students'relativistic space-time view.By introducing a specific case of“simultaneous paradox”in the teaching of special relativity,this paper emphasizes that the event itself does not depend on the reference frame,and the reference frame is just used to describe the spatio-temporal coordinate of events,which helps students to understand the absoluteness of event and establish the relativistic space-time view.
